Abstract. This paper presents retrospective simulations and future projections of daily time series of discharge and stream temperature for 52 278 reaches over the Loire River basin (105 km2) in France, using a physical process-based thermal model coupled with a hydrological model. Retrospective simulations over the 1963–2019 are based on the Safran meteorological reanalysis over France. 21st century projections are based on a subset of the DRIAS2020 ensemble projection dataset, derived from the Euro Cordex data set through the ADAMONT statistical bias correction. Such a dataset at this large scale and high spatial resolution stands out from existing datasets, and is the first one in France derived from a physical process-based thermal model. The dataset is freely available for other studies and can be downloaded as NetCDF format from https://doi.org/10.57745/LBPGFS (Seyedhashemi et al., 2022a).

Short summary
This paper presents pas and future dataset of daily time series of discharge and stream temperature for 52 278 reaches over the Loire River basin (100,000 km2 ) in France, using a thermal and hydrological models. Past data are provided over the 1963–2019. Future data are available over the 1976–2100 period under different future climate change models (warm and cold, intermediate, and hot and dry) and scenarios (optimistic, intermediate and pesimistic).
